Prophet: pip install fbprophet fails on osx 13.6

[ifuchs]

I am running OSX 13.6 (High Sierra) and Anaconda python v2.7.

_pip install fbprophet_ gives:

Warning: left-hand side variable (name=cp_idx) occurs on right-hand side of assignment, causing inefficient deep copy to avoid aliasing.
Warning: left-hand side variable (name=m_pr) occurs on right-hand side of assignment, causing inefficient deep copy to avoid aliasing.

Can anyone please tell me how I can get this to install?

Usually the source of this issue is that PyStan is not working due to the C++ compiler not working properly.
You can check if PyStan is working with

import pystan
model_code = 'parameters {real y;} model {y ~ normal(0,1);}'
model = pystan.StanModel(model_code=model_code)  # this will take a minute
y = model.sampling(n_jobs=1).extract()['y']
y.mean()  # should be close to 0

The install is a little more complicated with Anaconda because it has a separate build environment from system python. The easiest way to install fbprophet in Anaconda is through conda forge:

conda install gcc
conda install -c conda-forge fbprophet

Does that work?

Was having problems both with installing fbprophet and running pystan. I can confirm that the solution suggest by @bletham worked for both problems. Big thanks!

@bletham could you please help, maybe your solution is close to the one I am looking for.

I think this issue is related to compiler:

I am running mac os 1.9.5

tried to install gcc compiler via conda:
`conda -c conda-forge gcc -n myenv``
then 
`conda -c conda-forge fbprophet -n myenv``

still same error with :
`/usr/lib/libSystem.B.dylib`


pystan indeed failed , same error:
